Application l'filed Jiune 12,

To all 'whom t may concer/t:

Be it known that I, DAVID BLooM, a citizen of the United States, andaresident of Berkeley, county of Alameda,"and Staterof California, rhaveinvented a new and useful Closure for Containers, of which the followinis a specification.

iy inventionrelates in general to closures for containers and hasarticular reference to an improved means or effec-ting a posi- While theinvention is applicable to an unlimited different type of containers,fo-r the purpose of illustrating the salient features of the idea theclosures will be herein described and illustrated as applied to jellyand the like tumblers or glasses.

The primary object of the invention is to provide a closure which willeffect a positive seal and which may be produced in quantity lots at amodest cost so that the commercial possibilities of the invention may berealized to the fullest extent. Another feature of the invention residesin the simple manner in which it is applied, which will enable theclosure to be used by housewives aS well as packers operating on a largescale.

The invention possesses further features which will appear as thedescription now proceeds with reference to the accompanying drawing, inwhich Figure l is a view in side elevation and Vartly in section of asocalled jelly glass illustrating the application on the preferredembodiment'of the iiivention; Figure 2 is a top plan view of the cap;I'Figure 3 is a horizontal section. through the cap; Figure 4 is adetail view illustrating the application of a supplementary protectingcap and Figure 5 is a view in vertical section of a slightly modifiedform of container illustrating the application of the invention.y

Referring now to the drawing in detail, (5) represents the containerwhichhas previously stated, for the purpose of illustration I haveelected to show as an ordinary jelly glass or tumbler. It is highlydesirable to seal the container with paraffin in order to effect apositive air tight closure, not onlyto protect the contents of thecontainer but also to exclude air to prevent fermentation of thecontents or other de teriorating results.

According to my idea I propose to use a 1922. Serial No. 567,669.

cap (6) for the open top of the container, the cap being producedpreferably from parchment paper,but other material may prove just aseffective, for instance, a cloth gauzemay be employed. In any event thecap is made by stamping or` otherwise form- -ing the material to leavean insert (7) with an outwardly'projecting flange (8) at the upper edgethereof. The insert part of the cap is made of Substantially the samediameter as that of the open end of the container and is adapted to beinserted therein with the fiange (8) turned Adownwardly over the outeredge of the container as best shown in Figure l, and to anchor or fixthe cap in the container Iproposeto coat or otherwise' apply an adhesivesubstance to the under side of the flange (8) so as to stick thedownwardly turned flange to' theside of the container. The adhesivesubstance may be applied at the time the caps are made up, orindividually at the time the cap is to be used. vThis is, of course,immaterial so far 'as concerns the spirit of the invention.

Itis of course, known that paraffin is an appropriate sealing agent andI therefore propose to take advantage of the quality of the same incombination with the cap. To realize this effect I perforate the insertpart of the cap as at (10) by making small openings at spaced intervalsaround the sides of the insert part and also as at (ll) by making smallopenings in the bottom of the in- Sert. If desirable a large opening(12) may be used in the bottom. When the cap has been adjusted in placeon the container and, of course, after the container has been filled,and it might be well to mention here that the container should not befilled to the top but a space should be left between the container andthe bottom of the insert, the melted paraliin is poured into the hollowof the insert part of the cap and the same runs through the perforationsand occupies the space between the contents (A) and the bottom of theinsert and also between the Sides of the insert and the inside of thecontainer. Suiicient paraffin is used to imbed the insert part of thecap, as shown to best advantage in Figure I. It is desirable that theparaiiin occupy the whole of the space beneath the bottom of the insertand the contents of the container as well as the sides of the containerand the sides of the insert. Where the word paraffin is used, it

should,lbe considered as qualifying any like substancel that would beappropriate,

As a supplementary covering or protecting cap I can use a device, vasvbest shownat (13) in Figure 4, which Willslip overthe cap (6) and rotectthe same.

For some ood stuffs, it makes no differ- `ence Whether the parafiincontacts directly `or the like (15) so as to 'separate the paraffin fromthe contents; Aside from the introduction of this disc between thecontents and the paraffin, the invention embodies the samecharacteristic features.

I claim: y
